raturen 10".1, hvilket, med den ovenfor fundne Værdi 
af a, der neppe kan antages at forandre sig med Tiden, 
giver en Nulpunkt-Correction af + 0.31. For Tids- 
rummet fra 17. Juli til 20. August ere Correctionerne 
aabenbart større end for, i Medium + 0.54 for Tem- 
peraturen 1096, hvilket giver en Nulpunktcorrection af

Jeg har ogsaa beregnet Nulpunktcorrection af hver 
enkelt af de i 1876 gjorte Sammenligninger med Nor- 
malthermometret, sat disse Værdier op i Curve og der- 
efter udregnet Correctionerne for de enkelte Aflæsninger 
paa No. VII fra Dybet. Se ovenfor under Miller-Casella 
No. V. Men der vandtes ingen gjennemgaaende større 
Nøjagtighed, efter de af andre samtidig anvendte Ther- 
mometres Angivelser. De med No. VII 1 den første Del 
af Rejsen 1 1876 maalte Temperaturer staa saaledes til- 
bage for de øvrige i Nøjagtighed.

at the 10’.1; and this, with the above 
determined value of a, which can hardly be supposed to 
temperature 
vary with the time, gives a zero-correction of + 00.31. 
For the period, July 17 to August 20, the corrections 
are evidently greater than before, the mean being + 09.54 
for the temperature 10.6, which gives a zero-correction 
of + 0.64. Accordingly, I put 
for June 21 to July 11 OS +6 Opn = Coos 6 
aya! gar MIN == se Gris 
for July 17 to August 20 C = + 0°.64 — 0.0088 t, 
and get MF = + 02.07. 
I have also- computed the zero-correction from each 
comparison made in 1876 with the Standard-Thermometer, 
drawn curves for these values, and then calculated the 
corrections for the several readings of No. VII in the 
deep sea (see above, Miller-Casella No. V). But no 
invariably greater accuracy was attained, judging from the 
indications of the other thermometers observed simultane- 
ously. The temperatures measured with No. VII on the 
first part of the cruise in 1876 do not equal the others 
in accuracy.
